Error ‘Task could not be reserved’ when opening a new UI5 task in BPM Inbox

Hello,

Some time ago we changed the human tasks of our BPM process from Visual Composer to UI5. Since then the users have the issue that when opening a fresh task from the BPM Inbox they get this error:

The screen is loaded but without the data. The user has to close the error, close the task screen and select the task from the inbox again. The second time the data is loaded and the screen is displayed correctly.

To me it seems that the task appears in the inbox before all the data is loaded. If the user waits a bit longer before he selects the tasks there is no issue.

Has anybody experienced this behaviour?

The error log shows:

Caused by: com.sap.glx.core.kernel.api.TransitionLockingException: Unable to upgrade lock (OID = dfaa9a6c-9790-11e7-c815-00002511ea8e, separation = dfaa5101-9790-11e7-ac40-00002511ea8e, class = com.sap.glx.adapter.TaskAdapter:Task_0_SetStatusReservedOrNoStock2_52b6e863abd8160a9136f2b1c4884ec3, timeout = 2500).

Our system has version PO 7.40 SP14.
